The secret of TENZ is the stairs - the elevations between the threads.

These steps specifically create a smaller friction area, which significantly reduces the screwing-in resistance. The alternating loading and unloading creates a unique oscillating screwing-in movement – which brings amazing benefits on several levels. 

The unique feature is that the wood fibres are gently displaced instead of being drilled or milled. The result is better interlocking between the screw and the wooden component. 

Quite waterproof!

“This is a timber construction screw that specifically relies on its thread which makes for an out-of-the-box technology that is noticeably different in its use.”


“When placing the first screw, you may not notice much of a difference but you will when placing the hundredth and that includes differences in the utilisation capacity of existing equipment.”


“For innovative projects made of the living building material wood, you need equally perfect screws to achieve planning goals.”
